Heartbeat: Another Sleepy, Dusty, Delta Day

SYNOPSIS

When a man dies falling from a bridge Joe discovers the deceased and his girlfriend were implicated in a baby's disappearance three years previously. Foul play is suspected when the man's post-mortem reveals injuries consistent with a recent fight, and deeper delving suggests someone still believes the couple were responsible for the missing child. Elsewhere, Peggy's new look and odd behaviour causes a stir.
